Where does Long Island get drinking water from?
Groundwater Aquifers
Long Island’s Only Source of Drinking Water: Groundwater Aquifers. The water that flows from every single spigot in Nassau and Suffolk County comes from groundwater aquifers and nowhere else. These aquifers are ours to protect. Nothing is more important than clean water to drink.
Where does Suffolk County drinking water Come From?
All water the Suffolk County Water Authority delivers to customers comes from porous underground sand and gravel formations known as aquifers. There are three major aquifers found beneath Suffolk County. The deepest aquifer is the Lloyd aquifer, which ranges from 200 to 1,800 feet below land surface.
What are the three main aquifers on Long Island?
The Three Major Long Island Aquifers: Nassau and Suffolk counties obtain their drinking water from three major aquifers underlying Long Island which constitute a sole source aquifer. The aquifers are, from the shallowest to the deepest, the Upper Glacial, the Magothy and the Lloyd aquifers.
Does Long Island have aquifers?
Long Island’s aquifer system is comprised of several freshwater zones, or “aquifers”, generally ranging in increasing depth from the upper glacial, North Shore, Jameco, Magothy, and finally the Lloyd aquifer.
Where does Nassau County water come from?
Nassau County gets all its drinking water from the water stored in the porous soil beneath Long Island. This fresh water source is called ground water. The geological formations which store the large quantities of water are called aquifers. Nassau County uses three major aquifers for its drinking water.
Why is Long Island water so bad?
The most common contaminant of Long Island groundwater is a group of chemicals known as VOCs (volatile organic compounds). These are generally considered carcinogenic and/or toxic chemicals.These chemicals are known for their role as solvents for other industrial chemicals.
Is Suffolk County well water?
Individual on-site private wells provide water to approximately 50,000 year-round and seasonal homes in Suffolk County. In areas that lack a public water supply system, comprehensive water quality testing is conducted at all new realty subdivisions proposed with private wells.
Is the Lloyd aquifer confined or unconfined?
The Lloyd aquifer is the only true confined aquifer. It is separated from the Magothy by a thick clay layer known as the Raritan Clay.
How many different aquifers are present in Long Island name them?
It comprises three major aquifers, an Upper Glacial aquifer at the top, the Magothy aquifer in the middle and a deep less accessible Lloyd aquifer lying just above the Paleozoic metamorphic basement rocks. There are two major confining units.
Is Long Island water contaminated?
“Western Nassau County is up to 17.5 parts per billion when the drinking water standard is currently 1. Also, it has all three chemicals. So unfortunately they are getting the trifecta of water contamination. “We object to the public being told that contamination in our drinking water is safe,” she continued.
Which of the two aquifers on Long Island would be more prone to contamination?
Unconfined aquifers generally are much more vulnerable to contamination than confined aquifers. For a well in a confined aquifer, the farther the well is from the unconfined area, the less vulnerable it is to contamination.
How deep is the aquifer on Long Island?
approximately 2000 feet
The total depth of the Long Island Aquifer System is shallowest on the north shore (approximately 600 feet) and deepest along the south shore (approximately 2000 feet).
How Does Fire Island get water?
Most of the drinking water on Fire Island is now provided through Suffolk County Water Authority (SCWA), which supplies water to the majority of people in Suffolk County. Their drinking water supplies are tested to ensure that federal, state and local water quality standards are met.
Where does America get their water from?
The top row of cylinders represents where America’s freshwater came from (source) in 2015, either from surface water (blue) or from groundwater (brown). You can see most of the water we use came from surface-water sources, such as rivers and lakes. About 26 percent of water used came from groundwater.
Where does NYC get its water?
New York City gets its drinking water from 19 reservoirs and three controlled lakes spread across a nearly 2,000-square-mile watershed. The watershed is located upstate in portions of the Hudson Valley and Catskill Mountains that are as far as 125 miles north of the City. Learn more about our Water Supply System.
Where is the Lloyd aquifer?
Long Island
The Lloyd aquifer (Lloyd Sand Member of the Raritan Formation), is the oldest of the Cretaceous age formations on Long Island. It extends from central Kings, northwestern Queens and Nassau, and northeastern Suffolk Counties to the east and south (fig. 3).
Can you drink Nassau County water?
Bottled water in New York State must meet the same water quality requirements of the New York State Sanitary Code that apply to tap water. Please be sure that the label has been certified by the New York State Health Department for sale. The certification identification is on the label as “NYSHDCERT #000”.
What is the Lloyd aquifer?
The Lloyd Aquifer is the purest, deepest and most limited aquifer serving Long Island. Long Beach relies solely on water pumped from the Lloyd, to meet the needs of 34,000 residents.
Is there fluoride in Nassau County water?
Does Nassau County add fluoride to the water? No, not that we detected. 3rd party independent testing found that this utility exceeds health guidelines for this drinking water contaminant. 1,2,3-Trichloropropane, also known as TCP, is an organic “Man Made” chemical found in some groundwater supplies.
What does it mean when water is distilled?
purified water. Distilled water is a type of purified water that has had both contaminants and minerals removed. Purified water has had chemicals and contaminants removed, but it may still contain minerals.Distillation boils the water, and then condenses the steam back into a liquid to remove impurities and minerals.
